AUTOMOBILE HORN.

APPLICATION FILED DEO.13.1906.

' to produce a generally-improved horn of this ous parts comprised in the same and adapted I UNITED STATES IRA E. STUMP, OF CLEVELAND, OHIO.

AUTQMOBlLE-HORN.

To all whom it may concern: Be it known that I, IRA E. STUMP, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, l have invented certain new anduseful Improvements in Automobile-Horns, of which the following is a specification. My invention relates to improvements in automobile-horns designed to be blown' by the exhaust from .the motor passing through a suitable pipe or tubing connected thereto or by air contained in an ordinary air-compression bulb similarly connected thereto. The invention relates. more particularly to what may be termed a divisional horn, comprising a series of fluid-pressure chambers provided with adjustable valve-openings by means of, which their relative pitches may be made such as to produce a chord or chime when sounded together. The paramount object of the invention is class adapted to produce any desired itch or quality of tone by manipulation of t e varito produce a proper speech, character of tone.

With these ends in view the invention consists in the novel construction, arrangement, and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the ap ended clairrs. Y

eferring to the drawings forming a part of this specification, Figure 1 is a lan view of the improved horn; Fig. 2, a ongitudinal sectional view; Fig. 3, an end view taken through line 330i Fig. 1, with-the adjustably-mounted lips removed for the purposes of clearer illustration of parts; Fig. 4, a per spective view oione of the adjustably mounted lips; Fig. 5, area-r end view; Fig. 6, 3}; sectional view taken through line 6 v6 of i 1. S imilar characters of reference designate like parts throughout all the figures of the drawings. 7 V

The improved horn comprises a cylindrical main body portion 1, carrying on its front and rear ends fie nged caps or heads 2 and 3, respectively. The main body portion 1 con tains a plurality of longitudinally-extending I tubes 4, preferably three in number, as

blending, and

- openings 16 of the head or cap 3.

shown in the resent embodimentof the invention, and aving their ends abutting or 1 impinging against the caps or heads 2 and 3.

IPatented March 12, 1907.

The tubes 4 are adapted to form tubular fiu1dpressure chambers 5 and should fit snugly against each other and against the adjacent inner walls of the. body portion 1' throughout the entire lengths thereof, so as to form fluid-tight longitudinally-extending chambers 6 between the outer peripheries of tletubes and the inner periphery of the main body portion of the horn.

The tubular chambers 5 are brought into communication with the chambers 6 by means of notched o enings or recesses 7,

formed in the ends t ereof adjacent to the front cap or head 2, so that the chambers 6 form a practical continuation of the adjacent tubular chambers 5, thus giving a relatively long length to the several fluid-pressure chambers in a relatively short-horn body.

The several fluid-pressure chambers may be graded as to length. and the different itches in tones arising from the gradation in ength regulated to produce. a proper or desired blending or chime by means of vent of valve openings 8, formed in the horn-body 1 and communicating with the several chambers 6. The valve-openings 8 are adapted to'be increased or decreased in size or opened and closed by means of slide plates or valves sides 10, terminating in friction-flanges 11, abutting against the tubes 4 and adapted to support the platesin proper position against Eh?! inner periphery of the cylindrical horn- Therear flanged cap or head 3 is provided with inlet openings or slots 12, communicat ing with the tubular chambers 5, and the-size 9, provided with depending ofsaid slots is adapted to beincreased or decreased for varying orregulating the blending and character of tone produced by, means of slidably and adjustably mounted lips or tongue-pieces 13 ,secured 3 by means of thumb-screws 14, passing throughslots 15 and taking into threaded The operating fluid is directed 13 from slots or recesses 17, fornie,d by shallow notches or recesses in the abutting or impinging end 18, of triangular shape in cross-section, of the receiving or inlet tube or pipe 19.

The tubes 4, together with the caps or heads 2 and 3 and impinging inlet-tube 19, are securely fastened and held in proper position by means of a central longitudina lyto the capor head over and I against the edges of the lips or tongue 'pieces extending rod or bolt 20, threaded at its ortion and communicating with said .chamfront end and provided with a nut 21 and liars. 6o having, an eye or cross opening 22, taking 7.
